2018 Surabaya churches bombings

The 2018 Surabaya churches bombings occurred on 13 May 2018 in three churches in Surabaya, Indonesia, when a family of six Islamic State suicide bombers attacked the Innocent Saint Mary Catholic Church (SMTB), the Indonesia Christian Church (GKI), and the Surabaya Central Pentecost Church (GPPS). 13 people (including the 6 perpetrators) were killed in the attacks, while 43 were injured.

The suicide bombers were father Dita Uprianto, mother Puji Kuswati, and children Yusuf Fadil, Firman Halim, Fadilah Sari, and Pamela Rizkita, who had returned from Syria after being trained how to carry out suicide bombings. The first attack occurred at 6:30 AM, when Fadil and Halim, riding on a motorcycle, detonated their bomb in front of the entrance of the SMTB Church after being stopped by a security guard, killing a child and a security officer. The second occurred at 7:45 PM, when Kuswati, carrying two bags, hugged a security officer at the GKI and detonated her explosives. Not long after, her two daughters detonated their explosive devices. The security officer survived with critical wounds. The third (and most powerful) blast occurred at the GPPS at 7:53 AM, with Uprianto crashing through the gates in a car and detonating his explosives among the parked vehicles in the parking lot. Two people were mortally wounded in this attack.

The Surabaya churches bombings were the deadliest terrorist attacks in Indonesia since the 2005 Bali bombings. At 8:00 PM that same day, a bomb exploded at an apartment complex in Sidoarjo, killing three people in a single apartment room, while two children in the same room survived. The police suspected that the family in that apartment was planning a similar attack, but their bomb exploded prematurely and killed three of them.
